Ideas (most are somewhat jokes):
-Gingerbread house (like the house creating spells)
-Create sweets
-Magic sweets (like goodberry)
-Jawbreaker (thrown/sling ammo spawn)
-Flesh to gingerbread (like flesh to stone, but more sweet and crunchy)
-Molten sugar (ray form of fireball)
-Gingerbeing ( summons a small creature of candy (also possibly candy elemental))
-Candy-like (resistance to bludgeioning, but more attractive to being eaten or bitten)
-Sticky solution (entrapment or similar, might harden over time)
-Sugar Rush (speed increase followed by fatigue)
-Rock Candy Prison (either full life or entrapment in sugar like a crystal, danger of cunsumption either way though)
-Too-Tart (repels creatures that use taste mostly (like serpents))
Maybie I'll think of some more...
